Since upgrading from 2022 to 6.2, and now 6.3, I’ve had this error appearing in one of my scenes:
Render Graph Execution error
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)
It shows up when the scene has been active for 2 or 3 minutes, and isn’t due to any user input. It’s like Render Graph just decides it doesn’t want to play any more.
As far as I can tell it’s post processing that’s causing the issue. Turn it off and it doesn’t crash (at least, not as quickly). What’s confusing to me, though, is that I have an almost identical setup in another scene which doesn’t seem to have the same error. Same canvas (Screen Space - Camera), same camera (shown below). I have tried rebuilding the scene from scratch, but the problem reappeared as soon as I checked post processing.
As far as I can tell, it only shows up in the editor. Builds seem fine, but of course it’s impossible to tell if it would crash if I left it run for longer. It also appears to only happen in the one scene.
No additional information is given in the error, although it’s always followed by this one:

Any clues about where to start digging to fix this would be greatly appreciated. Thanks!
Edit: Added more info as I figured stuff out. I would add a post processing tag if I could.
